'''Interstate&nbsp;37''' ('''I-37'''{{refn|Some sources use "IH-37", as "IH" is an abbreviation used by TxDOT for Interstate Highways.<ref>{{cite web |author = Transportation Planning and Programming Division |date = n.d. |url = https://www.txdot.gov/inside-txdot/division/transportation-planning/highway-designation/glossary.html |title = Highway Designations Glossary |publisher = Texas Department of Transportation |access-date = May 20, 2020 }}</ref>|group=lower-alpha}}) is a {{convert|143|mi|km|adj=on}} [[Interstate Highway]] located within the [[South Texas|southern]] portion of the US state of [[Texas]]. The highway was first designated in 1959 as a route between [[Corpus Christi, Texas|Corpus Christi]] and [[San Antonio]]. Construction in the urban areas of Corpus Christi and San Antonio began in the 1960s, and the segments of the Interstate Highway in rural areas were completed by the 1980s. Prior to I-37, the route between Corpus Christi and San Antonio was served by a combination of [[Texas State Highway 9|State Highway&nbsp;9]] (SH&nbsp;9) from Corpus Christi to [[Three Rivers, Texas|Three Rivers]] and [[U.S. Route 281 in Texas|US Highway&nbsp;281]] (US&nbsp;281) from Three Rivers to San Antonio. As a result of the construction of I-37, SH&nbsp;9 was removed from the [[Texas state highway system|State Highway System]] (the designation would be reinstated to another highway in 2014).

The highway begins in Corpus Christi at [[U.S. Route 181|US&nbsp;181]] and [[Texas State Highway 35|SH&nbsp;35]] and heads north to San Antonio, where it ends at [[Interstate 35 in Texas|I-35]]. Beyond I-35, the freeway continues as US&nbsp;281 to northern San Antonio as a major [[freeway]]. In Corpus Christi, the highway provides access to the downtown area, the [[Port of Corpus Christi]], and [[Corpus Christi International Airport]]. In San Antonio, it provides access to [[Downtown San Antonio]], [[Brooks City-Base]], the [[Alamodome]], the [[Tower of the Americas]], the [[San Antonio River Walk]], the [[Alamo Mission|Alamo]], and, by extension via US&nbsp;281, [[San Antonio International Airport]]. The route provides an important connection between I-35 and the [[Texas Gulf Coast]] as well as one of the few [[Limited-access road|limited-access]] [[hurricane evacuation]] routes away from the southern Texas coast.

==Route description==
I-37 starts near the [[Texas Gulf Coast|Gulf Coast]] in Corpus Christi and heads northwest toward San Antonio.<ref name="TxDOT"/> It links [[South Texas]] to the northern parts of the state via [[Interstate 69E|I-69E]], [[U.S. Route 77 in Texas|US&nbsp;77]], and [[U.S. Route 281 in Texas|US&nbsp;281]]. The highway functions as one of the few freeway hurricane evacuation routes for the southern Texas coast. It roughly parallels [[U.S. Route 181|US&nbsp;181]], which both begins and ends at I-37, and US&nbsp;281.<ref name="Anywhere"/>
[[File:I-37 north of Corpus Christi.jpg|thumb|left|A rural segment of I-37 between Corpus Christi and San Antonio]]

Unofficially, I-37 begins at an intersection with Shoreline Boulevard on the edge of [[Corpus Christi Bay]]. It then heads west as a surface street for three blocks where it becomes [[slip road|entrance and exit ramps]] which connect to the freeway.<ref>{{Google maps|url=https://maps.google.com/maps?saddr=Unknown+road&daddr=Unknown+road&hl=en&ll=27.801273,-97.395505&spn=0.005476,0.008969&sll=27.800409,-97.395859&sspn=0.005476,0.008969&geocode=FT46qAEduusx-g%3BFe4uqAEdRs4x-g&t=h&mra=me&mrsp=1,0&sz=17&z=17|title=East of I-37 in Corpus Christi|access-date=April 20, 2013}}</ref> I-37 begins officially at the [[Gore (road)|gore point]] for these ramps, which is part of an interchange complex that also represents the southern ends of US&nbsp;181 and [[Texas State Highway 35|SH&nbsp;35]].<ref name="TNRIS">{{cite web|url=http://www.tnris.org/get-data?quicktabs_maps_data=1|title=Maps & Data|year=2012|publisher=Texas Natural Resources Information System|access-date=April 20, 2013|format=[[ESRI shapefile]]|archive-url=https://web.archive.org/web/20130530105748/http://www.tnris.org/get-data?quicktabs_maps_data=1|archive-date=May 30, 2013|url-status=dead}}</ref>

It heads west from US&nbsp;181 through Corpus Christi and intersects two freeways, [[Texas State Highway 286|SH&nbsp;286]] (the Crosstown Expressway) at exit&nbsp;1C and [[Texas State Highway 358|SH&nbsp;358]] (Padre Island Drive) at exit&nbsp;4A. The highway turns toward the northwest after the SH&nbsp;358 interchange roughly parallel to the south of the [[Nueces River]]. Just prior to leaving the Corpus Christi city limits, it intersects and has a short concurrency with US&nbsp;77 (future I-69E). US&nbsp;77 (future I-69E) merges with I-37 as a freeway from the south at exit&nbsp;14A northbound and exit&nbsp;14 southbound; the two continue to the north and split after crossing the Nueces River. The Interstate continues to the northwest as US&nbsp;77 (future I-69E) continues to the northeast at exit&nbsp;17.<ref name="Google Maps"/>

I-37 transitions to a rural setting once outside of the Corpus Christi city limits on its way to [[Mathis, Texas|Mathis]] and [[Lake Corpus Christi]]. It continues on to the northwest and intersects [[U.S. Route 59 in Texas|US&nbsp;59]] (future [[Interstate 69W|I-69W]]) east of [[George West, Texas|George West]] at exit&nbsp;56. It begins paralleling US&nbsp;281 to the east before the two intersect at exit&nbsp;72 and have a concurrency north of [[Three Rivers, Texas|Three Rivers]] near [[Choke Canyon Reservoir]]. [[Alternate U.S. Highway 281|Alternate US&nbsp;281]] (Alt. US&nbsp;281) splits off from I-37 near [[Sunniland, Texas|Sunniland]] at exit&nbsp;76 and parallels I-37 before rejoining north of [[Campbellton, Texas|Campbellton]] at exit&nbsp;92 southbound. The two routes remain concurrent until US&nbsp;281 splits off at exit&nbsp;104 northbound to head to [[Pleasanton, Texas|Pleasanton]], while I-37 bypasses the city to the east. After US&nbsp;281 leaves toward the northwest, I-37 turns to the north toward [[San Antonio]].<ref name="Google Maps"/>

[[File:I-37, I-410 interchange, San Antonio, Texas.JPG|thumb|left|I-37 and I-410 interchange on the southeast side of San Antonio]]
As I-37 enters the San Antonio city limits, it intersects the northern terminus of [[U.S. Route 181|US&nbsp;181]] at exit&nbsp;132 southbound (this is according to the [[Texas Department of Transportation]], or TxDOT; the [[American Association of State Highway and Transportation Officials]], or AASHTO, extends US&nbsp;181 northward to the northern terminus of I-37). Continuing to the north, it intersects [[Interstate 410|I-410]], the inner loop around San Antonio, at exit&nbsp;133 at a [[stack interchange]]. At this junction, the Interstate once again runs concurrently with US&nbsp;281 which had been concurrent with I-410. Heading north through the south side of San Antonio, I-37 provides access to [[Brooks City-Base]] (formerly Brooks Air Force Base). After exit&nbsp;135, a [[cloverleaf interchange]] at [[Texas State Highway Loop 13|Loop&nbsp;13]], the freeway turns toward the northwest. The highway intersects [[Interstate 10 in Texas|I-10]], which is concurrent with [[U.S. Route 90 in Texas|US&nbsp;90]] and [[U.S. Route 87 in Texas|US&nbsp;87]], at exit&nbsp;139 at a stack interchange on the southeastern corner of Downtown San Antonio. After the interchange, it once again heads north on the east side of downtown. It passes near the [[Alamodome]], [[Tower of the Americas]], [[San Antonio River Walk]], and [[Alamo Mission in San Antonio|Alamo]]. I-37 ends at the northeastern corner of downtown at exits&nbsp;142A and 142B at a junction with I-35. US&nbsp;281 continues to the north as a freeway and provides access to [[San Antonio International Airport]] and later far north central Texas.<ref name="Google Maps"/>

From I-410 to I-10 in San Antonio, I-37 is designated the '''Lucian Adams Freeway''', after the [[World War II]] veteran. Adams is a native of [[Port Arthur, Texas|Port Arthur]] and received the [[Medal of Honor]] for his service in France, along with the [[Bronze Star Medal]] and [[Purple Heart]], for his gallantry during the [[Battle of Monte Cassino]].<ref>{{cite web |author= Staff |url= http://www.cemetery.state.tx.us/pub/user_form.asp?step=1&pers_id=11141 |title= Lucian Adams |publisher=[[Texas State Cemetery]] |access-date= February 27, 2008}}</ref> From I-10 to its northern terminus at I-35, it is designated the Staff Sergeant [[William J.

==History==
Prior to I-37, the routing between Corpus Christi and San Antonio was covered by [[Texas State Highway 9|SH&nbsp;9]] from Corpus Christi to [[Three Rivers, Texas|Three Rivers]] and [[U.S. Route 281|US&nbsp;281]] from Three Rivers to San Antonio. Beginning in 1971, sections of SH&nbsp;9 were officially removed from the State Highway System as I-37 was completed.<ref>{{TxDOT|SH|9|access-date=February 27, 2008 |link=no}}</ref> No sections of US&nbsp;281 were removed from the State Highway System as a result of the construction of I-37, but the two do share the same alignment at two different points between San Antonio and Three Rivers. Also, US&nbsp;281 was rerouted onto I-37 in San Antonio in 1978.<ref name="Google Maps">{{google maps |url=https://maps.google.com/maps?f=d&hl=en&geocode=2568522560958495253,27.801020,-97.395701%3B6464171849619486050,29.438726,-98.477498&saddr=I-37+N+%4027.801020,+-97.395701&daddr=US-281+N+%4029.438726,+-98.477498&doflg=ptm&sll=28.61835,-97.938615&sspn=3.187023,5.108643&ie=UTF8&z=8 |title= Overview map of I-37 |access-date= February 25, 2008}}</ref><ref>{{TxDOT|SS|536|access-date= March 8, 2008 |link=no}}</ref><ref>{{TxDOT|SS|537|access-date= March 8, 2008 |link= no}}</ref>

I-37 was first designated in 1959 to provide a route between San Antonio and Corpus Christi,<ref name="TxDOT"/> and construction began in the 1960s. The $11-million (equivalent to ${{Formatprice|{{Inflation|US-GDP|11000000|1969}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}) project to construct the interchange with I-10 was at the time the largest single contract in the history of the state highway commission.<ref name="statesman1965">{{cite news|title=SA Project Top Single Road Job|work=Austin Statesman|date=April 2, 1965|id={{ProQuest|1521826279}}}} {{subscription required}}</ref> The route was completed by the 1980s.<ref name="Anywhere">{{cite report |url= http://tti.tamu.edu/interstate_anniversary/white_paper/ |title= From Anywhere to Everywhere: The Development of the Interstate Highway System in Texas |last1= Beaumont |first1= Penny |last2= Brinkmann |first2= Rhonda |last3= Ellis |first3= David |last4= Pourteau |first4= Chris |last5= Webb |first5= Brandon V. |year= 2006 |publisher= [[Texas Transportation Institute]] |page= 32 |access-date= February 25, 2008 |format= PDF |archive-url= https://web.archive.org/web/20080107001953/http://tti.tamu.edu/interstate_anniversary/white_paper/white_paper.pdf |archive-date= January 7, 2008 }}</ref> The first sections of the freeway completed were in Corpus Christi.
